nothing to fear with the open passing. they still had point to pass mostly, just allowed it anywhere. some 70s beater camaro blew some parts on the track and lucky me picked up a screw in a tire. it was right in the rain groove in the center of my ad08 so got it plugged and patched and went back out. ended up setting a PR lap time again. brake ducts also seem to help. was a cooler day but i have never had my rear tires heat up more than my fronts and thats what happened today. cooling air is keeping the fronts temp down so have to start with a higher front pressure then before as it doesnt come up as much.
